AARON D. ORANE, OE NEWARK, NEW JERSEY.

HORSE-POWER.

Specification of Letters Patent No. 8,028, dated April 8, 1851. i

To all lwhom, t may conce/m `Be it known that I, AARON D. CRANE, of Newark, in the county of Essex and State of New Jersey, have invented a new and useful `Improvement in the Construction of a Horse-Power Machine, which is described as follows, reference being' had to the annexed drawings of the same, making a part of this specification.

Figure l is a view `of the left side `of the machine, and Figs. 2 and 3 of the right side.

The pulleys or rollers marked A, Figs. 1 and 2, are those which sustain the platform and horse, and transmit the power to the driving pulley B, Figs. 2 and 3, by means of cranks connecting the pulleys together by a bar as at C, Figs. l and 2. The cranks on the side in Fig. 2 are set quartering to those on the side in Fig. 1 for the purpose of assisting it over what is commonly called the dead center of a crank motion. Fig. 5 gives a side view of thepulleys'and cranks. The

` pulleys D, Figs.` l and 2 are for the purpose of supportingtheplatform while passing under the pulleys A, and the wheels or pulleys E, Figs. 1 and 2, `are larger `than the other pulleys, for the purpose of increasing the curve of the platform in its revolutions. A side view of these pulleys is given f in Fig. 6. A side view ofthe platform is given at F, Figs. l and 2. It iscomposedof pieces of woodf A top view of one is given in Fig.

7, together with two links of the chain.`

These pieces are connected together by a flat chain G, Figs; l and 2, by means of bolts, which form the hinge or joint ofthe chain by running through the center of each piece or block of `wood composing the platform. Each `piece or link ofthe chain` has a lip or flange on the lower side asin* Figs. 4 and 7, for the purpose of supporting and` keeping the 4"pieces composing the platform from turning on the hinge or joint, bythe weight Of the horse.

Fig. 3 gives a side view of the brakeused on the inside of the inner rim of the driving pulley B, as at H. An end View of the whifletree is given, as at I, the center Iof which' works on an upright aXle fastened in the middle of the shaft J which extends across the machine. In this shaft is an arm K connected by the rod L, with the end of the lever of the brake H as at M. When the horse draws on the whiiletree, the brake is raised; the axle in the center of the shaft J on which the whiflietree works strikes against the. cross bar N, thereby preventing the brake from raising morethan a proper distance.

The advantages of this machine are that it costs less, and that there is much less friction and wear in this than others now in use, from the fact that no cog wheels or rack is used,` and consequently much more power y obtained, the attritioncaused andadhesion existing between the platform and the rollers or pulleys, being found sufficient for transmittting "all the power a horse is able to give.` And that by the addition of the brake acting as agovernor, the motion of the machine is more regular and steady, thereby preventing the horse from falling on his knees when thework is taken off.

That I claim as my invention, and desire to secure by Letters Patent, is-

The manner of arranging and connecting the whiflietree and brake, so that when the horse isdrawing the brake is OH the wheel or pulley, and when not, is on, and acting as at governor, as hereinbefore described for the purposes' hereinbefore set forth.`
